Dual Band W5LUA Type Dish Feed, Model DSEDBFEED
This feed design is based on the work of Al Ward, W5LUA, and represents an efficient way to
use one dish on two different ham bands. Unlike
earlier multi band feed designs, W5LUA’s
design is capable of good performance on both microwave bands in use. In addition, the
higher isolation of this design, between 10 & 5.7 GHz simplifies installation requirements by
eliminating the need, in many cases, for a protective relay on the 5.7 GHz port. Isolation runs
over 30 dB and is typically 40 dB.
Note: All hardware is Stainless Steel unless otherwise noted.
BEFORE INSTALLING YOUR NEW ANTENNA, PLEASE BE SURE
TO READ THE ENCLOSED WARNING PAMPHLET.
INSTALLATION INSTRUCTIONS
1)
Unpack antenna feed assembly and observe the location of the connectors and probe
orientation. For horizontal polarization, the probes must be oriented parallel with the horizon.
(The connectors will stick out laterally on the antenna.)
